The genotypes of the parents are Aa (heterozygous) and aa (recessive homozygous).  
 For example:  
 If the purple flower is dominant phenotype, then A is a dominant allele for it and Aa is a genotype which will give the purple colour.
In this case, white flower is recessive phenotype with aa genotype.
If we cross Aa x aa
<span>The offspring is going to be Aa Aa aa aa (half purple and half white)</span>

A benign tumor differs from a malignant tumor in that a benign tumor
ale4655 [162]

Your answer is...

<em>A benign tumor is a noncancerous group of cells that does not spread any harmful substances to the impacted area nor anything at all. It is safe compared to Malignant tumors and typically cause no harm to the body.</em>

<em />

Benign tumor:

Although it is noncancerous, if it is applying pressure to any vitals such as the blood vessels or nerves, it causes an obstruction. Thus ending up having to require treatment occasionally but not in all cases. It is considered a "good" tumor since it does not cause any pain or any problems when it doesn't apply pressure.

Malignant Tumor:

A Malignant Tumor is known as cancerous, or just cancer. These can be spread around the affected area of tissue or throughout the body. It is uncontrollably spread and disease ridden tumor that destroy the body tissue of the person. If this moves into the bloodstream, it can lead up to spreading within the lymph nodes, causing even more damage.

What is one way scientists know that Maiacetus lived in the ocean?
IgorC [24]

Answer The species is known from three individuals, all of which were found in the Habib Rahi Rock Formation of Pakistan

Maiacetus is significant because of how well the skeletons were preserved. Over 90% of the bones from the male were found intact, which is almost unheard of for a specimen this old!

Their skeletons have all been found among fossils of sea-creatures which suggests they lived in the sea.

The fore-snout is starting to elongate. An elongated fore-snout is found in all modern whales and all transitional whales after Maiacetus.

Phenotypes:
KatRina [158]

Answer:

A: can be subject to environmental conditions.

Explanation:

Phenotype is a genetics term used to describe an individual's observable characteristics that result from interactions with the genotype and nonheritable environmental factors.

Phenotypes are the <u>manifested</u> <u>aspects</u> of the morphology, physiology, biochemical properties, behavior and ecological relationships of an organism.

Given these statements, it can be concluded that two organisms cannot have the same phenotype (not even twins), because there will always be, however small, a morphological or physiological difference between them.
